Worldwide cognizance to biodiversity has accelerated some time past decade. Agricultural biodiversity is an important a part of biodiversity for human survival, but has been ignored as a subject. This e-book presents a huge overview of present pondering on agrobiodiversity - what it really is, the way it is conserved, and the way it may be greater used in sustainable farming. It brings jointly contributions from a large geographical and disciplinary heritage. Emphasis is put on sensible interactions among parts of agrobiodiversity in quite a number farming platforms, illustrated via many case experiences. The ebook relates the evolution of agrobiodiversity and its profitable administration to the wider atmosphere and to the becoming have to preserve biodiversity in effective agricultural platforms. it really is crucial studying for ecologists, biologists and agricultural scientists.

Indices of diversity for polygenic traits (observed phenotypically) are useful when applied to traits of immediate interest, but not as indicators of overall genetic diversity (Table 3,1). Some phenotypic traits are determined by welldefined (usually single-locus) genotypes and are useful as genetic markers, but there are rarely, if ever1 enough of them in a given population to provide even minimal coverage of the genome. It is useful to consider farmers' ability to measure diversity. While plant breeders can measure and deploy genetic distinctness, this cannot be done directly by farmers.
3, from the simplest to the most complex. ically important gene pool - continue to evolve in southwest Asia. , Chapter 9, this volume). They vary from monocultures of single varieties (including plantations), crop multilines, landraces, varietal mixtures, intercrops, crop rotations, multiple crops, and polycultures (including home gardens) (see Plates 9-12). Let us consider some examples of crop-based agroecosystems and compare their biodiversity, in particular, the partitioning of their genetic diversity.
